Amol Dicalite Limited was established in the year 1979 to produce, for the first time in India, Perlite Filteraids and Perlite products under the technical and financial collaboration with an American company Grefco, Inc. USA, pioneers and world leaders of Perlite products. The company started commercial production in the year 1982. The Company’s Corporate Office is at Ahmedabad and the Plant is located at Kadi in Mehsana District, 50 kms., north of Ahmedabad.

The company makes steady progress in developing import substitution products in Filteraids and has successfully met the requirements of majority of users.  From a small beginning of 600 M.Tons per annum, we have now reached about 5,680 M.Tons and developed many new applications.  During this time the company's performance improved consistently and is a profitable organization.

The company also undertakes cryogenic insulation jobs.  It has specially designed Portable Plants to carry out ON-SITE jobs.  At present the company owns 7 such Portable Plants. Large jobs have been executed in a short period of time and the technical team has acquired a high degree of expertise in performing these jobs with required high precision working.
 
PERLITE ORE AND PERLITE PRODUCTS

Perlite, in its natural state, is a volcanic siliceous rock. When crushed and heated up to a temperature of approximately 930°C., it pops like “popcorn” expanding from four to twenty times its original volume.The expansion of Perlite takes place due to the presence of 2 to 6 per cent combined water in Perlite Ore. 
CRYOGENIC INSULATION

Raw Perlite is a siliceous volcanic glass, containing 2 to 5 per cent combined water. When rapidly heated to the proper temperature, the volatilization of the water, coincident with the softening of the glass, causes the Perlite to suddenly expand or “pop” into light weight cellular particles or “bubbles”. 
THERMAL INSULATION

The insulation is covered using different materials depending on the application, environment and aesthetic value desired by the customer.  Large projects on a turnkey basis are taken up which includes providing cold insulation using PUF and other materials.
